INSQUE(3) Library Functions Manual INSQUE(3)
insque, remque -- insert/remove element from a queue
Standard C Library (libc, -lc)
insque(void *elem, void *pred);
insque() and remque() manipulate queues built from doubly linked lists.
The queue can be either circular or linear. The functions expect their
arguments to point to a structure whose first and second members are
pointers to the next and previous element, respectively. The insque()
function also allows the pred argument to be a NULL pointer for the
initialization of a new linear list's head element.
The insque() and remque() functions conform to IEEE Std 1003.1-2001
The insque() and remque() are derived from the `insque' and `remque'
instructions on the VAX. They first appeared in 4.2BSD.
